1 square root of 20 (1√20)

Here we will show you how to calculate 1 square root of 20, which is the same as 1√20, which again is the same as 1 times √20. In other words, we will calculate 1 × √20.

We will not only calculate the 1 square root of 20 decimal answer, but we will also calculate 1 square root of 20 simplified. We will start by calculating the decimal answer to 1 square root of 20, as follows:

1. Find the square root of 20:
√20 ≈ 4.472136

2. Multiply 1 by the square root of 20:
1 × 4.472136 = 4.472136

1√20 ≈ 4.472136

To get the answer to 1 square root of 20 simplified, we first determine if √20 can be simplified, and then we multiply what is outside the radical (√) by 1 to get 1 square root of 20 simplified.

√20 can be simplifed to 2√5. Therefore, 1 square root of 20 simplifed can be calculated like this:

1 × 2 × √5 = 2√5

1√20 simplified = 2√5
